[p2-dev] Use p2 API and tests

[Genevieve Bastien <gbastien+lttng@xxxxxxxxxxxx>]

Hi,


I am a developer on the Trace Compass project and I am working on a 
feature to automatically install/update/uninstall experimental features 
(Eclipse plugins in an update site). I was thinking of using p2 for this 
of course.


My idea is to create a wizard that would list all features (in the sense 
of Eclipse feature group) of the update site with their current status 
(installed/upgrade available/not installed). The user would select the 
actions to do for each, and then I would call sequentially, if needed, 
the uninstall wizard, update wizard and install wizard with the 
appropriate operation.


First, does it sound like a good plan? I started implementing this and 
it works, at least with the install wizard, I haven't tried many wizards 
in a row yet. Any advice on this?


Also, I will need to unit test this and would like to use the p2 testing 
facilities. We are using a target platform. Are the o.e.e.p2.tests 
plugins published anywhere?


Thanks,

Geneviève
